The blower fan motor relay is being activated when the ignition switch is turned on.
Is the air speed low, medium or high?
Are you able to control the air speed with the blower switch?
Possible causes are :
1. Faulty blower switch, ( higher possibility).
2. Relay Yellow/Red wire shorted to body ground, ( this would result in the blower running at highest speed)
The air coming out of passenger floor position indicates a fault in the air outlet servomotor.
Is vehicle equipped with manual or automatic climate control?
